I was thinking last night about aggregating notifications, since NANS
appears to have vanished, and isn't quite what I want anyway. I was
thinking that a sensible way to handle them might be to send the first
notification immediately, but if another arrives within some timeperiod
then it will be delayed until the end of that timeperiod, when all
outstanding notifications could be sent together.

The simple way to do this would be for Nagios to remember events and 
whether it has successfully sent a notification for them. It could also 
check the notification plugin for failure and keep trying until it 
succeeds. This would also help to solve your problem, since a notification 
out of timeperiod could be delayed until it was in timeperiod, rather than 
dropped completely.

The alternative solution I came up with requires fewer changes to Nagios, 
and basically queues up events externally to Nagios (fed by a 
notify_command), but this requires either writing a daemon or using Cron 
to check the queue regularly; daemons are complex, and Cron jobs don't 
notify fast enough, so neither of these is perfect in my mind.

What do others think? Should Nagios take responsibility for queueing 
events, or should it happen externally?

Cheers, Chris.
